feat(catalog): add reasoning efforts for meta/muse-spark-1.1/1.2/contributor

Maps the three Muse Spark models to [minimal, low, medium, high, xhigh]
so pi-ai can surface graded thinking levels instead of off-only.

These ids are already MODEL_REASONING=true; without MODEL_EFFORTS,
thinkingMetadataForModel() returns an empty map and the footer stays
:off with no cycle via /thinking or Shift+Tab.

Upstream command-code@1.32.2 lists these models as Efforts: — (none);
this commit intentionally adds a pi-side policy mapping aligned with
the opencode/opencode-go provider catalogs (which ship
muse-spark@ minimal..xhigh). The catalog header notes it is normally
generated by sync:commandcode-catalog — happy to move this to a
separate override layer if maintainers prefer.
